Determine whether the following statements are true or false, and explain your reasoning.

(a) From the data summary, the distribution of the sample is not normal.

(b) This confidence interval (3.02, 3.42) is not valid since the distribution of the sample is not normal

(c) We are 99% confident that the average of the ideal number of children in a family answered by the 678 females in the sample is between 3.02 and 3.42.
